Modular upright for building structures and associated sliding safety grille

Abstract

The present invention relates to a modular upright for building structures and a sliding safety grille which can be obtained by assembling these uprights. In a preferred embodiment, the modular upright ( 10 ) comprises a pair of anti-cutting reinforcing elements ( 1 ) which are lined by U-shaped modular elements ( 3 ) alternating with joining elements ( 2 ) and fastened together by at least one anti-pulling element ( 6 ) sliding vertically between two joining elements ( 2 ), in the space between the surface of the reinforcing elements ( 1 ) and the U-shaped modular elements ( 3 ).

What is claimed is:  
     
       1. Modular upright for building structures, characterized in that the modular upright comprises at least one anti-cutting reinforcing element ( 1 ), a multiplicity of modular elements ( 3 ) which are shaped so as to line a portion of said reinforcing elements ( 1 ), a plurality of joining elements ( 2 ) provided with holes ( 4 ) through which the reinforcing elements ( 1 ) pass and means ( 5 ) for fastening to the modular elements ( 3 ) with which the modular units alternate in the vertical direction. 
     
     
       2. Modular upright according to  claim 1 , characterized in that the modular upright comprises end joining elements ( 2   a , 2   b ) provided with additional means ( 5   a , 5   b ) for fastening to a fixed frame ( 11 ). 
     
     
       3. Modular upright according to  claim 2 , characterized in that the additional fastening means comprise a wheel ( 5   a ) traveling in a rail ( 11   a ) of the fixed frame ( 11 ). 
     
     
       4. Modular upright according to  claim 2 , characterized in that the additional fastening means comprise a recess ( 5   b ) matching a shoulder ( 11   b ) projecting from the fixed frame ( 11 ). 
     
     
       5. Modular upright according to  claim 1 , characterized in that the modular upright comprises a pair of adjacent anti-cutting reinforcing elements ( 1 ), each lined by a multiplicity of U-shaped modular elements each having a cavity ( 3 ) arranged so that the respective cavities are facing and alternating with a plurality of joining elements ( 2 ), said reinforcing elements ( 1 ) being fastened together by at least one anti-pulling element ( 6 ) sliding vertically between two joining elements ( 2 ) in a space between the reinforcing elements ( 1 ) and the U-shaped modular elements ( 3 ) which cover them. 
     
     
       6. Modular upright according to  claim 5 , characterized in that the modular upright comprises tubular spacers ( 7 ) which are inserted between the anti-cutting reinforcing elements ( 1 ) and the modular elements ( 3 ) and are designed to keep the anti-pulling elements ( 6 ) fixed heightwise. 
     
     
       7. Modular upright according to  claim 1 , characterized in that the fastening means comprise lugs ( 5 ) shaped so as to match the internal profile of the modular elements ( 3 ). 
     
     
       8. Modular upright according to  claim 5  characterized in that the anti-pulling elements ( 6 ) are in the form of a rod with a double ring so as to embrace the reinforcing elements ( 1 ) of an upright ( 10 ) passing through the facing cavities of the modular elements ( 3 ). 
     
     
       9. Sliding safety grille, comprising a fixed frame ( 11 ), at least one upper guide ( 12 ) or a lower guide ( 13 ), horizontally sliding uprights ( 10 ) fastened to at least one of said guides ( 11 ,  12 ), so as to avoid the vertical displacements thereof, and to each other by means of connecting bars ( 14 ) arranged in pairs in an “X” shape, characterized in that the sliding safety grille comprises modular uprights ( 10 ) according to any one of the preceding claims. 
     
     
       10. Sliding safety grille according to  claim 9 , characterized in that the connecting bars ( 14 ) are fastened to the uprights ( 10 ) in the region of anti-pulling elements ( 6 ). 
     
     
       11. Sliding safety grille according to  claim 9 , characterized in that each connecting bar ( 14 ) interacts with three consecutive modular uprights ( 10 ) at the connecting bar's ends ( 14   a ,  14   b ) and in the connecting bar's central zone ( 14   c ). 
     
     
       12. Sliding safety grille according to  claim 10 , characterized in that the sliding safety grille comprises modular uprights ( 10 ) provided with tubular spacers ( 7 ) which are designed to keep the anti-pulling elements ( 6 ) fixed heightwise.
